Information

MMCX RF Connectors

MMCX connector is one series of RF connectors. This MMCX connector is jack/ female, and straight bulkhead type. Its design is to be terminated with RF Coaxial Cable by crimping to be MMCX adaptor RF cable. The applicable RF coax cable is RG178/ 1.48mm/ RG196 RF coaxial cables. Its plating is Gold over brass and the impedance is 50 ohm.

MMCX connector is kind of small in RF connector. MMCX Connectors has snap-on coupling design. Besides, MMCX jack crimp series still have Right angle jack , straight crimp jack, PCB mount jack, edge mount jack and SMT jack. MMCX Connector commonly is used for 0~3GHz. If you need higher working frequency, special mechanical design requests, or need to custom RF connector and RF connector cables, please contact us.

MMCX connector jack straight bulkhead crimp type can be terminated with RG178/ 1.48mm/ RG196 RF coaxial Cable to be RF Cable assembly. It can transmit RF Signal well in telecommunications. MMCX RF connector is most commonly used in GPS internal Antenna, GSM external Antenna or GPS/GSM application these kinds of RF industry.

Cable Assembly

Cable assembly Instructions Crimp type

Assembly Instructions: Step1
Step1. All parts of MMCX connector are shown as the top line

Assembly Instructions: Step2
Step2. Strip the cable into center conductor, insulator, shielding three parts per recommended stripping dimension shown in connector spec.

Assembly Instructions: Step3
Step3. Slide the ferrule onto the cable jacket.

Assembly Instructions: Step4
Step4. Put the cable inner conductor into the main body to touch contact pin and then solder it, and then spread out the shielding onto the knurled part.

Assembly Instructions: Step5
Step5. Proceed the first open-short test to make sure signal transmit well.

Assembly Instructions: Step6
Step6. Slide the ferrule over the main body and crimp it to let it become tighter.

Assembly Instructions: Step7
Step7. Wear the heat shrink onto the ferrule and then shrink it.

Step8. Do the open-short test of every cable assembly before QC examination.
